Aliments pour prévenir ou combattre le cancer

Les mûres aideraient à prévenir le cancer du côlon et de l'oesophageUsing animal models (rodents) of cancer development, researchers at Ohio State University showed that animals whose diets were supplemented with black raspberries had a 60 percent reduction in tumors of the esophagus and up to an 80 percent reduction in colon tumors (60% de réduction des tumweurs de l'oesophage et 80% pour les tumeurs du côlon.). Clinical trials are now underway to determine whether the berries will prevent the development of esophageal and colon cancer in humans, says study leader Gary D. Stoner, Ph.D., a researcher and professor of internal medicine at the university. Les bleuets contiennent des molécules qui aident à prévenir le cancer du côlon.A compound found in blueberries shows promise in animal studies of preventing colon cancer, according to a joint study by scientists at Rutgers University and the U.S. Department of Agriculture. The compound, pterostilbene, is a potent antioxidant that could be developed into a pill La molécule pterostilbene est un puisssant anti-oxydant qui pourrait être développé en pilule.with the potential for fewer side effects than some commercial drugs that are currently used to prevent the disease, according to study leader Bandaru Reddy, Ph.D., a professor in the Department of Chemical Biology at the university. Les composés dans les extraits de graines de raisins peuvent aider à combattre le cancer de la peau en boostant le système immunitaire. Chemicals obtained from grape seed extract show promise in animal studies as a way to prevent sunlight-induced skin cancer when used as a dietary supplement, according to researchers at the University of Alabama in Birmingham. In studies using mouse models of ultraviolet-light-induced (non-melanoma) skin cancer, mice that were fed diets supplemented with the grape seed compounds, a group of antioxidants called proanthocyanidins, showed a reduction in tumor number (up to 65 percent fewer) and size (up to 78 percent smaller)(une réduction du nombre des tumeurs de 65% et de la grosseur de celles-ci de 78 %) in comparison to control animals that did not receive the compounds, the researchers say. The compounds appear to work by inhibiting suppression of the immune system caused by ultraviolet light exposure, says Santosh Katiyar, Ph.D., an associate professor in the university's department of dermatology.

Boir du jus de pomme non-filtré peut aider à prévenir le cancer du côlon.Researchers in Germany say that drinking two to three glasses of cloudy apple juice (unfiltered) per day may help keep colon cancer at bay. In a ten-week study using a mouse model for colon cancer, animals that were fed either cloudy apple juice or a potent extract of the juice showed a 38 percent and 40 percent reduction (respectively) in benign tumors of the small intestine, an indicator of its potential to fight colon cancer, in comparison to control animals that were given water instead of juice, according to Clarissa Gerhäuser, Ph.D., a researcher with the German Cancer Research Center in Heidelberg. The anticancer effect is likely due to a potent class of antioxidants called procyanidins, the researcher says. A widely publicized recent study by a group of researchers in Poland found that cloudy apple juice also is richer in antioxidants -- up to four times higher -- than clear apple juice. Le jus de pomme non-filtré est jusqu'à 4 fois plus riche en anti-oxydants.
